Video: Falcon 9 hot fire

A SpaceX Dragon supply ship packed with nearly three tons of experiments, crew provisions and supplies will remain on the ground until at least Friday morning to allow more time for NASA flight controllers to troubleshoot a problem with an electrical distribution unit on the International Space Station.

One of SpaceX’s most loyal commercial customers, the European-based telecom satellite operator SES, remains committed to flying a spacecraft aboard a “refurbished” Falcon 9 booster as soon as the company resumes rocket flights, officials said.

The mission comes a day after launching 23 Starlink satellites from Launch Complex 39A. Liftoff of the Starlink 6-52 mission from Space Launch Complex 40 happened at 6:40 p.m. EDT (2240 UTC).
